Transcutaneous Spinal Cord Stimulation for Blood Pressure Augmentation Immediately After Spinal Cord Injury

Sponsor: Markey Olson

Summary

In the treatment of spinal cord injury (SCI) patients in the hyperacute setting, it is imperative to closely control mean arterial pressure (MAP) to ensure adequate spinal cord perfusion in the absence of properly functioning autonomic innervation. Standards of care in literature have historically been to maintain a mean arterial pressure of 85-90 mmHg for 5-7 days after injury. Currently in the ICU setting, this is typically performed using intravenous vasopressors like norepinephrine. Although effective, vasopressors carry risks including arrhythmias, peripheral ischemia, and prolonged ICU management. Transcutaneous spinal cord stimulation (tSCS) has emerged as an alternative method for blood pressure augmentation in SCI patients, recently completing a clinical trial in chronic SCI patients with incredibly promising results. tSCS has yet to be trialed in the ICU setting, but it is expected that patient response should be similar to the chronic setting. This prospective feasibility study will evaluate whether tSCS can acutely increase MAP in adults with acute traumatic SCI admitted to the ICU. During a single study session, participants will receive transcutaneous stimulation while standard vasopressor therapy is maintained at a constant dose. A neurocritical care physician will be present throughout testing to ensure patient safety and standard clinical management. The primary objective is to determine the feasibility and acute hemodynamic effects of tSCS in this population. Primary outcome measures include change in MAP from baseline and time to hemodynamic response following stimulation. Secondary outcomes include changes in heart rate, stimulation tolerability, adverse events, and participant-reported comfort and overall experience. Data collected from this feasibility study will be used to assess the safety and practicality of implementing tSCS in the hyperacute SCI setting and to inform the design of future clinical trials evaluating tSCS as an adjunct or alternative strategy for blood pressure augmentation in critically ill SCI patients.
